To al-lwhom it may concern: Be it known that I, MATTHEW J. DOLPHIN,

, acitizen of the United States, residing in the city, county, and State of- Xew York, have invented certain new and useful Improvements in Postniarhing-Machines, of which the following is a specification.

My invention relates to that class ofmachines constructed for automatically marking or canceling mail matter; and my inventionconsists in certain im I'OVBIIIGIltS in such ine;

machines fully set fort hereinafter and illustrated in the accompanying drawings, in w ich: 1

Figure 1, is 'aplan of my improved ma Fig.2, is'an" enlarged plan, the framepartly hrokenaway, showing the parts more immediately connected. with the stampingdevices; Fig. 3, is the same as Fig. 2, showing {the-parts in different positions; Fig. 4, is an QDdAii-om; Figs 5, is a'sectional plan on the 5, Fig. 4; Fig; 6,.is a plan of part of theseparatingdevicesFig. 7, is an eleva non of the ghjard of the separating devices.

The frame A, of the machine is suitably constructed to support the working parts iereinafter described, which are driven from a shaft B, operated by any suitable motor.

In the'c'onstruction shown the letters are carried ina vertical position between trav eling bands or belts 1', 2,'the belt 2,pass1ng around a drum 3, and also around a drum 4,

- hich constitutes the impression bed or bearings.

opposite sides of the band 2, rollers 12, 13, .one or both of which may have a yielding or elastic covering a, while one, for instance, the roller 13, is carried by a swinging frame 93, upon which bears a spring 14, that forces the roller against the band. These presser rollers can be duplicated at 12 13 and a spring 94, aids to' insure the adhesion of the letter to the band 2, so that there shall be no slip between thetwo, the spring and rollers V yielding as required by any additional thick- "ness-of the letters.

The die or cancelingstamp is'u on a prin t ing roller 5, which is carried by ut with its shaft slightly movable in a frame C, pivoted at one end by a vertical pivot pin X to a yoke C, the latter having a horizontal trunnion x rocking in a bracket C secured to the base-plate or table if. By this arrange mentof oints the frame C, can swing upon the pin 00 to carry the printing roller 5,'t'o and from the letter, and can also rook upon the horizontal pin or trunnion-x* {so as to hold the face of the printing seller against the face of the letter when the latter is thicker at one edge than at the other. The printing roller is upon a shaft.15,-,that passes through slots 16, in the ends of the upperand lower plates 121 and 120 of the 31118 C, which lates ai'econnected together by a cross-piece 105, and stud 23 and said shaft also passes through plates 150'and 151 of a frame E, into a slot in which extends a pivot pin 152, Fig. 8, and springs 34, 34, extend etween pins upon the frames C and E, and

draw be the atter and draw forward the plateC, so as to tend to hold the shaft 15, at the ends ofthe slots 16, farthest from the belt 2. Against the frame C, for instance against the cross-piece 105, thereof, hear springs: 17 ,coiled around rods 18, and conne ctedwithcthe frame and sliding through a stationaryipostnj-M), upon the platform 11, which springs tend to force the frame to.- ward the belt 2, and to bring the printing 'op osite sides of the belt 2,

roller 5, against the letter upon the belt which in such case constitutes the bed. The frame and the printing roller are held in the position shown in Fig. 2, with the roller awav 'engages a portion of the frame C, which position between the plates of the frame (3,,

and a shoulder 22,:of said catch'20, enga es a lip 23, upon a stud 23*, carried by tie frame C, as shown in Fi s. 2 andv 3. s ring 29, bears against the catch 20, to t now it to the position shown in Fig. 2, and

the tripping devlce is shown in the form of a lever l), pivoted to a fixed stud 25,011 the plate 123, and provided with a lip'26, en-t gaging the projecting end of the catch 20, so that when the end of a letter strikes the end of the tripping lever the inner-end of the latter moves with the letter and the outer edge swings and carries the catch '20 away from the lip 23, after which the springs 17, will force the frame. C, and the printing roller toward the letter.- In order that the edge of the letter even when of thin mat erial may act positively upon the tripper, 1 provide two rolls 27, 27*, which bear upon the as close as possib eto the end 'of the t1l3p81 so as to hold the end of the letter close y to the belt and prevent the letter from crumpling or s ringing away out of proper contact wit 1 the tripper. To accommodate letters of different thicknesses the roller 27, Fig. 3, is carried by an arm 28, which is forced toward the belt 2, by a spring 131.

Just below the tripper is a roller 27, which bears upon the belt 2, and holds the letters against the belt ,at" that point. A spring 30, connected with the tripper serves. to restore the latter to the position shown in Fig. 2, when the frame C, is swung back.

' It willbe noted that the distance between the fulcrum of the tripping lever D, .and the point where it bearsupon'the catch 20, is much shorter than the distance between said fulcrum and the end that contacts with the letter, and that the lever D, bears upon the catch at its extreme end, whereby I obtain such a leverage that the thinnest letters will exertsufiicient power upon the tripping lever to swing back the catc 1.

It is necessary after the impression has been made uponthe letter to carry the printing roller away from the path of the letter to its normal position outof said path and away from contact with the letter or belt, thereby permitting the 'tripper to return to from the belt by means of a catch that its normal'position before the letter has passed beyond the tripper, as otherwise the letter would be reprinted or the belt would be smeared and mark the faces or opposite s'ides of the succeeding letters. This is effected by the rotation of the printing roller itself, which roller has a cam 31, having an abrupt shoulder 32, which cam is connected to the roller or to the shaft 15, and as the roller revolves the cam bcarsupon the stationary pin 33, on the frame C, and gradually forces outward the frame until the lip 23, engages 'the shoulder of the catch 21),

which catch is thrown into this position by the spring 29. After this the shoulder 32, of the cam passes the pin 33, when. the springs 34, 34, will draw back the frame-H in the direetion of the arrow 8, moving therewith the shaft 15, and printing roller 5. and carrving the latter away fromthe path of the let- It will be seen that this action is per-"5 missible in consequence of the elongation of.

ter.

the slots 16, which permitfirst the frar'neC. to be swung backto ahmited extent and locked'-wi-thout moving the feed roller, and

then permit the printing roller and itsshal't to be drawn back without moving the frame.

It will be seen that these actions take place during a single revolution of the printing roller, and that at the termination of this revolution the roller is restoredto its normal position, so that after a letter has been marked the printing roller and the .trippcr which bears on the letter after the parts are restored to normal position will immediately be in position to operate upon the following letter. In order to position exactly the printing roller at the end of its movement, itis provided with a stop 35, F igs. 2 and}. which makes contact with the shoulder 36. on the stationary rod 37, and prevents funther movement until the frame C. is thrown forward, as show-n in Fig 3. when the stop will be in position to pass the shoulder.

Heretofore in some machines of this class the friction of the letters has been'dependcd upon to rotate the stamping roller and lift the frame C, away from the bed, as for instance in the machine described in Laass & Heys patent No. 388,366, but the necessary frictional cont-act of the stamping roll and roller by the letter. h

Different means may be employed for throwing the stamping roller into action with positive driving appliances upon or by the action of the tripper when the latter is moved bv a letter. One means for this purpose is illustrated in the accompanying drawing. Fig. =1, in which 38, IS a drivingrollcr the v driving shaft of which is connected by a tie yi- I u devices described hereinafter against the drum 38, when the drum lo; and.

ble connection 39, with the shaft of the impression roll 4, and i0, is a parallel drum the shaft of which is connected by a flexible connection 41, with the shaft 15, of the stamp roller. Normally the drum 40, is out of con tact with the drum which is driven constantly fronr the shaft of the impression roller 4, but when a letter strikes the tripper.

the drum all). through suitable intermediate is brought the stampingroller will be positively revolved the extent of single revolution on the completion of which the drum .40, may be'carried to its normal position. .T he surfaces of thedrums 38 and 40, are of rubber so as'to insure friction and the drum 40, is. carried by a frame F, pivoted to a stud .42, engages with its inner end bearing on a leaf spring 26*,

which prevents shock ahd too great move mentof the tripper; and as'the latter swings a shaft 46, is rocked to bring an arm 47, against the lever 44, and push the latter in the'direction of the arrow, 5, away from the shoulder 43, when the frame F, will swing inward under theaction of a spring 48, bring ing the roller 40, against the drum 38. As the roller 40, begins to revolve with the roller 38, a cam 40, upon' the shaft of the roller 40, will bear upon a stud 50. of the frame F, and the latter will gradually be forcedoutward in t-he direction of its arrow, 5, until the pointof the cam passes the stud 50, when a spring 51, that bears upon the sliding bearing of the roller shaft will force the roller :40, away from the roller 38, the frame F, having meanwhile been engaged by the catch 44, and locked in its normal position.

The shaft 46, that swings the catch 44, is

ope ated from the tripper tlmmgh the medium of the upper swinging frame C, when the latter is released by the action of the tripper. A stud 53, Fig. 2, on the frame 0, bears upon an arm 54, on the shaft 46, Fig. 9, so that when the frame C, swings inward the shaft 46, is turned.

Inasmuch as the frames" F, G, move tocertain extent independently ofeach other whitethe shafts carried by the two frames are coupled together, it is'necessary to use a flexibh "coupling, and a flexible coupling is alsoused between the rollersifis'a'nd 4, inasmuch as -the roller or drum 4, must swing hesprinting roller in proportion to t, 9 van thickness of the mail matter I, therefore, mount" the shaft of the roller 4,

' in a swinging name 55, againstvhich bears a spring 56, that tends to keep the; frame against a bearing, as a stop 107, while; a

shown in Figs, 1 and 6.

spring 30*, Fig. 4, connected with a bracliet extending from the frame 55, is also attached to the adjusting screw 30 that permits any desired tension to'be obtained.

Although I have shown the flexible connections 39, 41, in the form' of short shafts.

and universal-joints 58, any other forinof flexible connections may be used. It will also be evident that different appliances may be used for carrying the frictional driving rollers 38, 40, into'and out of contact under the action of the tripper, and that any other means for positively driving the stamping roll from a positively moving part'of the machine would effect the same result, and although I have shown a swinging frame carrying the printing roll and a cam carried with said roll for swinging said frame it will be evident that other means may be employed for effecting this result.

In those cases where the stampin roll turns in lived bearings so that said roll only has an intermittent rotary. motion the within described driving means or their e-(piival-ntS may be employed for imparting such motion and for arresting the printing roll at the termination of eachrevolution.

Inasmuch as the printing roll with 'the construction described has a swinging as well as. an intermittent rotary motion, it is necessary to arrange the inking rolls so as to maintain constant contact of said rolls, notwithstanding the changing of the posit-ion of the die, I, therefore, carry the inking roller 60, upon a shaft on the frame E, and carry the distributing rolle'r'61, upon a swinging frame 62, swinging upon the shaft 63, of the reservoir roller 64,-which is constantly driven by a band g, a spring 65, maintaining the frame 62, in such position that the distribnt ing roller 61, constantly bears upon both of the rollers 60, 64. The roller 60, only makes contact with the raised die on the stamp roller 5, and the latter is normally in a position with the die out of contact with the roller 60, but the latter is driven constantly from the rollerfil, through the roller 61, so that-itis not necessary to de )end on the 1110-. tion of the stamp roller to (rive theinking roller. l

While the letters may be fed to the carriers laterally over the plate or chute 8, as before described, I prefer in someinstances to make use of a separator of the character illustrated in my Letters Patent No. 408,405, dated 'Aug. 6, 1889'. In such separator there'are two rollers r, r, the former traveling peripherally in the direction of the bands 2, and the latter in the reverse direction,'as herein In order to press the letters morefirmly against the conducting roll r, and insure their movement with the latter as well as toprevent them (especially when of tilrm -oi flimsy material from being vertical belt 2.

This spring shield acts asa guard to prevent. thin flimsy letters from beingturned back or crumpled when brought against the roller r. i
